Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] In order to ensure the safety and reliability of glass in use, whether it is physically tempered glass used in buildings, automobiles, furniture, chemically strengthened glass used in electronic products, or glass containers used in daily life, it is necessary to increase the final strength of the glass. Before the process (such as: physical tempering, chemical strengthening), make a safety chamfer on the edge of the glass to prevent possible edge cracks from growing, thereby improving the safety and reliability of the glass.

[0041] Based on the above considerations, the present invention ...

Abstract

The invention is applicable to the technical field of touch screens, and provides a method for manufacturing a capacitive touch screen glass panel. The method comprises the following steps of A making a plurality of one-side or two-sided chamfers of the glass panel, and enabling the chamfers to be matched with the size of the glass panel on a glass substrate according to needed size of the glass panel; B conducting chemical strengthening treatment on the glass substrate processed by the step A; and C cutting and splitting the glass substrate processed by the step B to obtain the capacitive touch screen glass panel. The two-sided chamfers of a finished glass panel are directly made on the glass substrate during pre-manufacture of the glass substrate, the chamfers and the substrate are strengthened together to enable the chamfers to be provided with strengthening layers, so that border strength of the glass panel is fundamentally improved, and then follow-up procedures such as cutting and splitting are carried out.

Description

technical field [0001] The invention belongs to the technical field of touch screens, in particular to a capacitive touch screen glass panel and a manufacturing method thereof. Background technique [0002] There are two types of capacitive touch screens: bonding type and single-chip type, which are described as follows: [0003] The bonded capacitive touch screen is to attach a glass panel (cover glass) on the sensor glass of the capacitive touch screen through OCA optical glue. This glass panel is only used to protect the capacitive touch screen. The glass panel The (cover glass) process is generally: slicing (cutting the glass substrate into a glass panel)---split---grinding the glass panel---chamfering---polishing---deep strengthening---printing ink; The process of sensor glass is generally: slicing (the original glass mother board is cut into a glass substrate) --- slivers --- grinding --- chamfering --- light strengthening --- coating --- Photolithography --- slicing...
